Alicia, a participant of the Mr and Miss Pride beauty contest, strikes a pose after walking the runway during rehearsals for the contest in Kampala, Uganda, August 1, 2015. “I am contesting for Miss Pride to fight against discrimination of the LGBTI community in Uganda”, Alicia said.

Fear of violence, imprisonment and loss of jobs means few gays in Africa come out. On Saturday August 8 members of the lesbian, gay, bisexual and transgender (LGBT) community emerge from the shadows as they celebrate Gay Pride near the capital Kampala.
